RUFUS PORTER, OF BILLERICA, MASSACHUSETTS.

CHEESE-PRESS.

Specification of Letters Patent No. 1,554, dated April 15, 1840.

T0 all 'whom z5 may concern Be it known that I, RUFUs PORTER, ofBillerica, in the county of Middlesex and State of Massachusetts, haveinvented a new and Improved Cheese-Press, of which the yfollowing is afull and exact description,

with references to the drawings thereof.

Two ports A B, three feet high, five inches wide at t-he bottom, buttapering on a curve nearly to a point at the top, and one inch thick,are placed in an upright position about twenty inches apart; the inwardedges being parallel to each other. These posts are connected by twosills C, at the bottom, and by a beam D at the top; and are supported bytwo cross sills or feet E F. A plank G, twenty inches long and eightinches wide, is placed in a horizontal position between the two posts,and is kept in that position by four guides H H, two of which areattached, in a vertical position, to each end of the plank. These guidesare fifteen inches long, three inches wide and one inch thick, andextend downward ten inches below the plank; each pair of guidespartially incasing one of the posts. Another similar plank I is placedten inches below and parallel to the rst; having also four similarguides J J J, which extend upward out side of the first four, which arepartially incased by these: these two planks thus constituting the bedand follower of the press. Two metallic double levers K K, eachconsisting of two curved levers connected by a cross-bar L, are attachedto the guides H by four fulcrum-pivots M. The levers pass between theturned by the crank P, the planks and guides are drawn up. vTwo frictionrollers RI. Y

are mounted between the heads of the double levers, and roll on theoutward edges of the posts, whenever the pressing apparatus is moved upor down. 1When the apparatus is permit-ted to descend by its owngravity, the rollers being pressed outward by the swell of the twoposts, the planks are made to approach toward each other, thus e'ectingpressure on a cheese or any other article that may be placed betweenthem; and this pressure is increased as the movement of the rollersapproaches a perpendicular direction.

Figure 2, in the drawing represents aside view of one of the levers Kwith the friction roller R, the fulcrum pivot M, andthe pin N.

I claim as original,

The mode of producing a pressure by means of the double levers, frictionrollers, and swelled posts, as above described.

RUFUS PORTER.
